Original abstract

A suitability of various fracture criteria in case of compressive loading conditions is performed in this work. Four fracture criteria were investigated: constant fracture strain, EWK, Oh and Xue-Wierzbicki. The first two ones are already implemented in PAMCRASH v 2005.1, while the later two had to be programmed as a user material. These models were applied to technological process of bolt head trimming. The numerical simulation was compared with the experimental results.
